SPECIFICATION forming partof Letters Patent No. 613,804, dated November 8, 1898.

To all whom it may concern.-

1Be it known that I, ALBERT MLLER, a subject of the Emperor of Germany, and a resident of Berlin, in the Empire of Germany, have invented certain new and useful Means and Improvements in Connection with Receptacles for Drawing off Liquids by Means of Liquid Carbonio Acid, of which the following is a full, clear, and exact description.

The present invention consists ofimprove ments in jugs and other household receptauids may be drawn off from Ithe same through the agency of liquid carbonio acid; and the device consists of the details of construction, as hereinafter more particularly set forth.

According to the present'invention a small receptacle filled with liquid carbonio acid and provided with a reducing-valve is attached to a cover made in one with or air-tightly closed onto the receptacle in question, which is further provided with a valve or tap for letting olf the liquid contained in the said receptacle, said liquid being driven out through the tap or valve by the pressure of the carbonicacid gas in the receptacle.

In order to render the present specification more easily intelligible, reference is had to the accompanying drawings, in which similar letters denote similar parts throughout the several views.

Figure l is a vertical section through acaskshaped receptacle for beer or the like, showing the arrangement of the carbonio-acid receptacle thereon. Fig. 2 is a side elevation of three receptacles in connection. Fig. 3 is a section through one form of reducing-valve which may be employed.

According to the present invention any kind of household receptacle whateversuch as jugs or pitchers of porcelain, earthenware, or glass or metal-may be employed, the same being provided with a hermetically-sealed cover having two nozzles thereon,as at s and h, one of said nozzles being for the reception of the carbonio-acid chamber and the other for the tap through which the contents of the receptacle are drawn off. The carbonio-acid chamber D is filled with liquid carbonio acid and provided with a suitable reducing-valve, one form of which is shown at Fig. 3, but further description of the same is not necessary, owing to its being fully described in another application, and a downwardly-projecting stem havingat its lower end an eX- terior screw-thread adapted to engage an interior screw-thread 'a of a tting screwed to the central nozzle 7i of the receptacle. The said lit-ting B is provided with an interior downwardly-extending tubular stem t, the lower end of which forms a seating for a conical or other valve r, having an upwardly-projecting stem fast to a horizontal plate o, having two small orifices o2. When the reducing-valve stem is tted to the sleeve B, the stem of the same depresses the plate of the valve and keeps the same open while the carbonio acid flows into the receptacle; but if it is required to remove the fitting and reducing-valve and to apply it to another receptacle and the same is taken off the fitting B the valve will be immediately closed by the interior pressure and by the action of its spring. Thus it will be seen that by means of the present arrangement of the checkvalve the reducing-valve-lnay be used in connection with any number of receptacles and may be fitted to or, taken off the same at any time without disturbing their operation. Thus, for instance, a half-iilled receptacle may be recharged, if desired. The downwardly-extending end of the stem of the chamber D is provided with a cock m. Normally the valve r will be pressed upwardly and held closed by the interior pressure of the beer in the receptacle.

In order to fill the receptacle, the beer may be poured through the fitting B, or the latter may be taken off and the beer poured into the jug. In the latter case the fitting should then be replaced and the carbonic-acid receiver or chamber screwed into the. upper end of the tting or sleeve B. When the cock'm is opened, carbonic acid will pass into the receptacle and press on the upper surface of the liquid therein, forcing the same up the pipe g, which extends nearly to the bottom of the receptacle, through the valve e, when the same isopened by hand, and out at the spout a into a glass or other receptacle. The cock or valve e is mounted in the housing C, screwed to the nozzle s of the beer-jug cover, said housing having therein a seat for the valve e, against which the same is normally IOO held by means of a spring d, bearing against a plate D on the valve-sleeve7 said stem carrying at its upper end a button it, which may be depressed by hand. Within the spring d is mounted on the stem of the valve e an india-rubber sleeve f, adapted to engage against a seating formed in the housing C when the valve is depressed and prevent the beer from escaping through the cover Z1. The valve o is further provided with a spring q, which tends to normally hold the same against its seating. When the carbonio acid passes through the holes o2 of the plate o, it opens the valve o against the pressure of its spring. When the but-ton lo is depressed, the beer will be forced up the pipe gand out at the spout ct. The housing C may be secured to the nozzle s by means of a sleeve 1', and the cap is tightly screwed to the upper part of the housing at f.

YVhen one carbonio-acid chamber is to be used for several receptacles, which may contain different sorts of beer, the stem of the chamber D is advantageously provided with a T-piece, as at l, to which a hose-pipe or india-rubber tube S is attached, which leads to the nozzle Z2 of the next receptacle or to the T-piece L of the next chamber, as at Fig. 2.

I claim as my inventionl. Adevice for drawing off liquids from ordinary receptacles consisting of an air-tight cover to the receptacle,having mounted thereon a draw-off cock with tube extending to approximately the bottom of the said receptacle, and having further a housing B mounted thereon with downwardly -opening checkvalve, having a plate at its upper end, an internal screw-thread to said housing, a reducing-valve having a stem with external thread to lit said sleeve and depress said plate when the said stem is screwed in the housing and hold said valve open in the man ner and for the purpose substantially as described.

2. The combination of a receptacle having an air-tight cover, two lugs or nozzles on said cover, a downwardly-openingspring-pressed valve in one nozzle and a carbonio-acid receiver screwed onto the said nozzle above said valves a stop-cock above said valve in the stem of the receiver a T-piece in the stem of said receiver below said stop-cock, and tubes in connection therewith to communicate with other receptacles, an outIiow-valve screwed to the second nozzle a downwardlyopening spring-pressed valve therein and downwardly-extending tube and spout thereon and means for opening said valve as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.

ALBERT MLLER.
